Just to be clear, there's no "10-minute rule" or other band-change rule 
in sweepstakes. There is a "1 transmitted signal at any time" rule that 
makes a M/2 or M/M which uses a single transmitted signal lock-out 
system perfectly legal in sweepstakes.

And of course, a second voice in the background calling CQ would clearly 
be a violation of the "1 transmitted signal at any time" rule
